[0024] When working, in the above-mentioned technology, an anti-static conveyor rack for producing plastic packaging bags needs to adjust the position of the self-locking slider on the slide rail when adjusting the position height of the plastic packaging bag placing plate. The adjustment process is relatively time-consuming. The structural design of the adjustment mechanism realizes the function of facilitating the adjustment of the height position of the placing plate 20. When the position height of the placing plate 20 is to be adjusted, the worm gear 33 is first driven to rotate by starting the motor 29. The worm gear 33 is meshed with the worm 32, so that the worm 32 rotates inside the fixed housing 27, thereby driving the worm 32 connected to the worm 32 to rotate. When the threaded rod 25 on the top rotates, the moving block 26 threadedly connected to the threaded rod 25 will move up and down, and the right side of the placement plate 20 is connected to the moving block 26 through the connecting rod 23 and the first connecting plate 24. The placement plate 20 will move with the movement of the moving block 26, so as to achieve the purpose of adjusting the position height of the placement plate 20. The bottom end of the worm 32 is rotatably connected to the inside of the fixed shell 27, the sleeve shell 28 is used to protect the worm wheel 33, and the support plate 31 is used to support the bottom end of the threaded rod 25, so that the threaded rod 25 can be more stable during the rotation process.

[0026] During operation, the retaining frame 34 is sleeved on the worm 32 to support and fix the worm 32 to ensure that the worm 32 does not shake significantly during rotation, so as to facilitate stable rotation of the worm 32 .

[0027] Furthermore, the connecting rod 23 is in contact with the fixed shell 27, and two groups of slots 35 are provided on the connecting rod 23. Long blocks 36 are slidably connected inside the two groups of slots 35. The long blocks 36 are welded and fixed on the fixed shell 27. The slots 35 and the long blocks 36 are both trapezoidal in design.

[0028] During operation, when the moving block 26 drives the connecting rod 23 to move, the long block 36 fixed on the fixed shell 27 will slide in the slot 35, and the contact between the long block 36 and the inner wall of the slot 35 is used to ensure the stability of the connecting rod 23 during the movement, so as to reduce the shaking of the connecting rod 23.

[0029] Furthermore, a second connecting plate 37 is welded and fixed to the left side of the placement plate 20, and the left side of the second connecting plate 37 is welded and fixed to a slider 38, and the slider 38 is slidably connected to a fixing column 39, and the bottom end of the fixing column 39 is welded and fixed to the base 1;

[0031] Furthermore, the cross section of the fixing column 39 is T-shaped, and the support column 21 is vacuum-designed;

[0032] During operation, the structural design of the fixing column 39 is used to limit the maximum movement range of the slider 38 on the fixing column 39, and the support column 21 adopts a vacuum design to reduce its own weight.

[0033] Furthermore, a fixing plate 30 is welded and fixed to the bottom end of the motor 29, and the bottom end of the fixing plate 30 is fixedly connected to the base 1;

[0034] During operation, the fixing plate 30 is used to support and fix the motor 29 so that the motor 29 can be more stable during operation.

[0035] Working principle: In the prior art, an anti-static conveyor rack for producing plastic packaging bags needs to adjust the position of the self-locking slider on the slide rail when adjusting the height of the plastic packaging bag placement tray. The adjustment process is relatively time-consuming. In this case, an anti-static conveyor rack for producing plastic packaging bags realizes the function of facilitating the adjustment of the height position of the placement tray 20 through the structural design of the adjustment mechanism. When the height of the placement tray 20 is to be adjusted, the worm gear 33 is first driven to rotate by starting the motor 29. The worm gear 33 is meshed with the worm 32, so the worm 32 rotates inside the fixed shell 27. This drives the threaded rod 25 connected to the top of the worm 32 to rotate, and the moving block 26 threadedly connected to the threaded rod 25 will move up and down. The right side of the placement plate 20 is connected to the moving block 26 through the connecting rod 23 and the first connecting plate 24. The placement plate 20 will move with the movement of the moving block 26, thereby achieving the purpose of facilitating the adjustment of the position height of the placement plate 20. The bottom end of the worm 32 is rotatably connected to the inside of the fixed shell 27, the sleeve shell 28 is used to protect the worm wheel 33, and the support plate 31 is used to support the bottom end of the threaded rod 25 so that the threaded rod 25 can be more stable during rotation.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
